Quote:
"[Margaret Perry] entered filmmaking in 1936 after her husband's death, and joined the NFB [National Film Board of Canada] in 1942 where she stayed until 1945. She was appointed director of motion picture publicity films for the government of Nova Scotia in 1945, and ran a one-person film unit until 1959. She produced more than fifty films before her retirement in 1969."
